With standard models available from stock, EnviroValor supports contractors and distributors.
Ready stock available. Fast delivery. Samples available upon request.
Designed for Practical Wastewater Aeration Applications
EnviroValor fine bubble disc diffusers are designed for practical wastewater aeration applications.
| Feature | Description |
|---|---|
| Fine bubble generation | Produces fine bubbles to increase gas-liquid contact area |
| Bubble size | Approx. 1–3 mm |
| Membrane material | EPDM membrane for wastewater aeration applications |
| Support body | Durable P.P. base structure |
| Backflow prevention | Self-sealing membrane design helps reduce wastewater backflow |
| Energy efficiency | Low headloss design helps reduce blower resistance |
| Installation | Suitable for fixed aeration grids and replacement projects |
| Supply | Standard models available from stock |
Oxygen Transfer Performance
The EV-270 fine bubble disc diffuser is designed to support efficient oxygen transfer.
| Model | EV-270 |
|---|---|
| Type | Fine bubble disc diffuser |
| Bubble size | Approx. 1–3 mm |
| Oxygen transfer efficiency | 25% at 4 m water depth with 2 CMH airflow |
| Oxygen transfer rate | 9.96 kg-O₂/hr |
| Design focus | High oxygen transfer, low headloss, stable aeration |
EPDM Membrane
The EV-270 uses a standard black EPDM membrane.
| Material | Standard black EPDM |
|---|---|
| Application | Municipal wastewater and general wastewater aeration |
| Elongation | 588% |
| Tensile strength | 1715 psi |
| Hardness | 60 Shore A |
| Thermal resilience | Approx. +3% volume change after 70 hours in 100°C boiling water |
| Heat aging resistance | Up to 140°C |
Self-Sealing Membrane Structure
The EV-270 does not rely on an additional external check valve.
| Function | Description |
|---|---|
| During aeration | Air pressure opens the membrane pores and releases fine bubbles |
| When air stops | The elastic membrane returns to a closed position |
| Benefit | Helps reduce wastewater backflow into the diffuser and piping system |
| Design advantage | No additional check valve component required |
